Two working documents are being developed, which are attached for information and comment (see Attachment 1 and Attachment 2). WP 5A looks forward to further collaboration in this area and would appreciate receiving information on relevant related activities that may be useful for the completion of the working documents. The next meeting of WP 5A will be held on 8-19 November 2010. Deadline for contributions: 1 November 2010 at 16.00 hours UTC.
